He's machining the cold side to fit a slightly larger compressor wheel. He told me over the phone that I might see around 4 psi of increased boost. I assumed with the fuel turned up and a larger exhaust I would see an increase in boost. Why would this not be the case?
you will have to reuse the TC05 hotside, there are only 3 turbos with the same pattern, all for the d55/d56 a td04, tc05, and a TF035.
TC05 is non wastegated, td04 and tf035 are internally gated.
TC05 hotside will fit a td05, you do NOT wanna reuse the tc05 center cartridge, was a horrible single bearing design. There is no real good reason to reuse the coldside, it has 2 boost nipples, but they can be pulled from another source.

turn the smoke screw, boost will go up lol
